UNITED STATES JAMES EDWIN GIBBS, OF CLIFTON FORGE, VIRGINIA.

SASH-FASTENER.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed December 20, 1906. Serial No. 348,761.

To all whom it may concern:

Be it known that I, JAMES EDWIN GIBBS, a citizen of the United States,residing at Clifton Forge, in the county of Alleghany and State ofVirginia, have invented a new and useful Sash-Fastener, of which thefollowing is a specification.

The invention relates to improvements in sash fastenors.

The object of the present invention is to improve the construction ofsash fasteners, and to provide a simple, strong and durable sashfastener, adapted to be cheaply manufactured, and capable of beingreadily applied to a window and of securely locking the upper and lowersashes thereof, either closed or open to a greater or less extent.

A further object of the invention is to provide a such fastener, which,while capable of use on windows having counter-balancing weights, willbe especially adapted for locking the sashes of a window not providedwith such weights, and which will enable either of the sashes of awindow to be either raised or lowered without unlocking or affecting theadjustment of the other sash.

Another object of the invention is to provide a sash fastener, whichcannot be left unlocked and which will effectually prevent one of pairof sashes from accidentally falling while the other is being adjusted.

The invention also has for its object to provide a sash lock havingindependently operable spring-actuated dogs, normally engaging thesashes and adapted to be disengaged from the same by a key, and toprovide means for enabling the dogs to be positively moved intoengagement with the sashes by the key, should the spring become broken,or otherwise inoperative.

With these and other objects in View, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawingz-Figure 1 is a vertical sectional view of a windowprovided with a sash fastener, constructed in accordance with thisinvention. Fig. 2 is a vertical. sectional view, taken substantially onthe line 2-2 of Fig. 1. Fig. 3 is a horizontal sectional view, takensubstantially on the line 33 of Fig. I. Fig. 4 is a detail view of aportion of the window frame, the sash fastener being shown in elevation.Fig. 5 is a detail perspective view of the supporting plate. Fig. 6 isan enlarged detail sectional view, illustrating the arrangement of thearcuate recesses and the rib or feather of the key. Fig. 7 is a detailperspective view of one of the dogs. Fig. 8 is an enlarged detail view,illustrating the construction of the intermediate connecting portion ofthe spring and the manner of mounting the same on the supporting plate.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

].1 designate similar interchangeable substantially L-shaped dogs,extending upwardly and downwardly and adapted to engage the upper andlower sashes 2 and 3 of a window 4;, the upwardly extending dog beingarranged to lock the upper sash and the downwardly extending dog thelower sash. The dogs arepivoted at their inner or proximate ends at thetransverse center of a supporting plate 5, and they have bills orengaging portions 6 at their outer ends for engaging the sashes.

The sash fastener is mounted on the window at one side'thereof, and theadjacent edges of the upper and lower sashes are provided with suitableopenings'or sockets, which may be formed by boring openings 7, or bycutting recesses 8. Any number of such openings may be provided toafford the desired adjustment of the sashes.

The supporting plate is mounted on the window frame or casing at theadjacent ends of the upper and lower sashes in position to be concealedby the same, when the same are closed, and the said supporting plate isprovided with upper and lower end openings 9, through which the engagingportions of the dogs project. The plate 5 is provided at the center witha substantially rectangular bearing 10, provided at opposite sides withhearing openings 11 and having a threaded opening 12 at the transverseconnecting portion or back. The openings 11 receive a key 13, which isprovided at its outer end with a suitable head and which is mountedadjacent to the head in a thimble 14. The thimble 14 frictionallyengages the walls of a horizontal opening of the window frame, and isthereby securely held in place without the use of screws, or otherfastening devices. longitudinal rib or feather 15, and the end of thethimble is retained on the shank or spindle portion of the key betweenthe head and the adjacent end of the feather or rib. The feather or ribis normally arranged in rear arcuate recesses 16 of the proximate endsof the dogs, which are provided with openings to receive the shank orspindle portion of the key. The key forms a pivot for the dogs, and theshoulders or end walls 16 of the arcuate recesses 16 are arranged inpairs and extend outwardly beyond the bearing faces of the bearingopenings of the dogs. The rib is adapted to engage the lower shoulder orend wall of the recess of the up per dog to swing the latter out ofengagement with the upper sash, and the key is adapted to be turned inthe opposite direction to cause the rib or feather to engage the upperend wall or shoulder of the arcuate recess 16 The key is provided with aof the lower dog to disengage the same from the lower sash. By thisconstruction, the dogs are operated independently to disengage them fromthe sashes, and one of the sashes may be adjusted without affecting theadjustment of the other sash.

The dogs are normally held in engagement with the sashes by a spring 17,but in order to enable the dogs to be positively moved into engagementwith the sashes by the key, should the spring become broken, orotherwise defective, the dogs are also provided with front arcuate slots18, having walls or shoulders 18 and the key is adapted to be pulled outof the openings of the dogs and the rectangular bearing and reversed toarrange its rib or feather in the recess 18.

The spring consists of upwardly and downwardly extending arms, spacedapart to engage the rear faces oi the dogs near the outer ends thereof,and connected by a horizontal transverse portion 19, which is providedat its center with a curved bend or loop 20, extending around one sideof the threaded portion of a screw 21, as clearly illustrated in Fig. 8of the drawing, and engaged by the head of the screw, whereby the springis securely clamped on the connecting portion of the rectangularbearing. The screw engages the threaded opening.

The supporting plate is provided at opposite sides of its inner or rearface with longitudinal enlargements 22, tapered from the center to theends of the supporting plate and forming inclined seats for the dogs,whereby the openings are maintained in alinement, when the key is not inengagement with the same. The dogs will be held on the seats by the armsof the spring, and this construction will be found advantageous inassembling the parts and when removing and replacing the key. The dogsare held from lateral movement on the seats by longitudinal flanges 23and the intermediate rectangular bearing.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent,

isz
